Phased genomes and pangenomes are enhancing our understanding of genetic variation. Accurate phasing and assembly in repetitive regions of the genome remain challenging, however. Addressing this obstacle is crucial for studying structural g...
Evidence of long-term purging of mutation burden in killer whale Orcinus orca genomes [0.03%]
杀伤鲸(Orcinusorca)基因组中长期清除突变负担的证据

Andrew D Foote et al.
Genomes of high latitude killer whales (Orcinus orca) harbour signatures of post-glacial founding and expansion. Here, we investigate whether reduced efficacy of selection increased the predicted mutation burden in founder populations with ...
Comparative analysis of gene family evolution demonstrates expansion of digestive, immunity and olfactory functions in the black soldier fly (Hermetia illucens) lineage [0.03%]

Structural variants such as chromosomal rearrangements and gene duplications can play an important role in the adaptation and diversification of organisms. Here, we used comparative genomics to study the functional implications of structura...
Last Glacial and Holocene dynamics override post-colonial disturbance in shaping genetic diversity of a heavily exploited palaeoendemic conifer, Lagarostrobos franklinii [0.03%]
末次冰盛世和全新世以来的种群动态而非殖民后的干扰塑造了近代遭受严重采伐的特有冷杉拉格罗斯特罗波斯 franklinii 的遗传多样性

James R P Worth et al.
The impact of past anthropogenic disturbance on the amount and distribution of genetic diversity is a key factor in determining the resilience of tree species to environmental change. This is particularly the case for narrowly distributed s...
Chromatin state dynamics of autosomes and the B chromosome during spermatogenesis in Pseudococcus viburni [0.03%]
Pseudococcus viburni有丝分裂过程中常染色体和B染色体的染色质状态动态变化

The mealybug Pseudococcus viburni is a plant-feeding insect with a non-Mendelian genetic system known as paternal genome elimination (PGE). In PGE, males eliminate their paternally inherited chromosomes during meiosis, transmitting only the...
Genetic structure and historical gene flow in Araucaria angustifolia populations across two Brazilian regions [0.03%]
两个巴西地区伞松种群的遗传结构及历史上的基因流动

Bruno Marchetti de Souza et al.
Araucaria angustifolia (araucaria) is a conifer tree of high ecological and social values in the Brazilian subtropical region. However, the species is threatened with extinction. We examined the genetic variability and gene flow between pop...
Investigating the effects of chimerism on the inference of selection: quantifying genomic targets of purifying, positive, and balancing selection in common marmosets (Callithrix jacchus) [0.03%]
嵌合体对选择推断的影响研究:量化三趾树猴(Callithrix jacchus)纯化、正向及平衡选择的基因组目标
Vivak Soni,Cyril J Versoza,Susanne P Pfeifer et al.
Vivak Soni et al.
The common marmoset (Callithrix jacchus) is of considerable biomedical importance, yet there remains a need to characterize the evolutionary forces shaping empirically observed patterns of genomic variation in the species. However, two unco...
